Rock physics explores the quantitative relationships of seismic, sonic or ultrasonic velocities to the petrophysical properties so as to predict beyond the existing data range facilitating the initial phase of seismic interpretation. This can be achieved through a forward or an inverse rock physics model, with the primary aim being linking the elastic properties of rocks to porosity, lithology etc. Therefore, rock physics is an integral part of reservoir characterisation, seismic reservoir monitoring and lithology discrimination.enRock PhysicsSandstonesCarbonatesSeismic InversionDensityThesis
